Well, 42pi is the result of multiplying 42 by pi, isn't it? In the default MthIO mode the calculator strives to display as many results symbolically as possible.

To convert a single result to decimal, press SD. To have all results come out in decimal, press SHIFT MODE 2 to select the LineIO mode.

### What formula do you use to calculate cylinder volumes

Volumes are any three dimensional measurement...

I Seriously doubt that I could get Pi ("pie") to print...
But I'll just GIVE YOU the number (much simpler)
Pi = 3.14159

Inches, feet, yards or meters.. all the dimensions need to be in the same values... So if you have an inch "ruler"...
That is just fine...!!

Your first step would be to determine the diameter of the inside of your cylinder in inches...
CONVERT that to the RADIUS by DIVIDING by 2...
Multiply that RADIUS by itself and then by 3.1416 = area of circle in INCHES... (radius "squared" x Pi = (square inched)

Then MULTIPLY the height (in inched) by the AREA...
EQUALS THE VOLUME in CUBIC INCHES...!!

But I'll just GIVE YOU a REFERENCE (much simpler)
mathematical constant ?
Area of circle

### I can get pi, but then when i need to multiply it by a number (example: 6), It just gives me that number, with the pi sign beside it. it wont give me an answer.

When in MathIO the calculator displays pi symbolically. If you want the numerical value of an expression, press [SHIFT][=], not just [=]. You can try pressing the [SD] key to toggle between fraction`/radical to decimal. You can also configure the calculator to use LineIO by default.
